View Full Version : javascript include (help!)

08-14-2006, 10:04 PM
This topic may have been covered, I did not find it.

I need an example from someone who knows how to do the following:

:confused: I need to know part of the javascript, such as say google adsense, gets saved into a .js file and what script gets placed in the <head> of the page for it (to call it up) and what do I use as a command to bring it back up again where ever I want it placed in the <body> of the page.:confused:

If you could provide an additional example besides google adsense so that I know what I should be doing everytime, that would be greatly appreciated.:o

Oh, I know that using php or ssi would be better yes. I would love to hear book recommendations (because more than likely I'll be ordering a few soon), and I have also tried posting something like this in abestweb's programmer's corner to no avail. Please help. I'd like to use javascript in my html pages without getting penalized by the bots and spiders.

Thank you,

I'm not 100% sure what you are asking but, this may address all or at least some of your questions:

Use a text editor to save the script, call it 'file_name.js' where 'file_name' can be any valid file name of your choosing. Substitute the name of your external .js file for some.js in the below:

<script src="some.js" type="text/javascript"></script>

Common problems arise when:

1 ) The script file is not in the directory specified. In the above example it must be in the same directory as the page(s) that use it. Below, it can be in the scripts directory off of the root of a domain:

<script src="http://www.somedomain.com/scripts/some.js" type="text/javascript"></script>

2 ) Opening, closing and/or 'hiding' tags are left in the external file. This means that you must strip:
</script>and any of their many variations from the beginning and end of the external file.

3 ) The external call (<script src="some.js" type="text/javascript"></script>) is not inserted into the page at the correct spot. The external call must be inserted at the same place on the page where the script was/would have been.

4 ) Paths to other files (if) used by the script are no longer valid due to its location. This is only a problem if the external script is kept in a different directory than the page it was working on when it was an internal script. To correct this, use absolute paths inside the script. Absolute path examples:



5 ) Inappropriately combining two or more scripts into one external file. Usually external scripts can be combined if one knows enough about scripting to do so properly. Even then it is possible to overlook something.

A rule of thumb when testing is, if it won't work on the page, it won't work as an external file either.

One other thing, if this is a DD script or any script that requires the credit remain for legal use, include the credit in the on page call, ex:

<script src="some.js" type="text/javascript">
* IFrame SSI script II- Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
* Visit DynamicDrive.com for hundreds of original DHTML scripts
* This notice must stay intact for legal use

Make sure to retain all the 'decorations', as these include begin and end javascript comment delimiters without which the script won't function.
